如果你要絕筆 ，你真係令我太失望........(絕不是諷刺) 喺現實ge社會裏，如果人唔互相依賴，試問誰又能夠在這個弱肉強食ge社會入面掙扎求存呢？你應該比我更加清楚ga~雖然我真係覺得你有d多事，但唔代表我憎你，要你絕跡。大家上嚟都係為咗求知識而唔係求氣，我絕唔希望因為呢d雞毛蒜皮ge事而傷大家和氣。最後一句，我真係希望你唔好再抱著'人地唔細心思考'ge心態，與其令自己和別人難受，倒不如大家互相幫手回答知識，對嗎？(如有失敬之處，請見諒!)

If you want to know why HK was annoyed, reread your question:
...don't use some stupid methods...
How do you feel if you want to help someone?

I simply directly copy from your homework or exam paper. Is that right???
You can try to find the answer from your textbook. I think that you have NOT try your best before raising a question in 知識+. There is no free lunch at all!!!!

本人向來喜歡做義工，幫助別人。但反觀現時很多人，不懂盡力而為而，第一時間就搵人幫手。
我以前做後生的時候，我師父鬧我。但他亦同我苦口婆心地同我說：「為你好，才會花力氣去鬧你；若果我連氣都省下來的話，你才要驚！」
可能我真的太多事了，或許我是時候抽身出來。或許我不再入知識+，我可能會更好。
HK在知識+絕筆
